DNA origami

Scientists in China have developed a simple method for time-lapse imaging of single molecule reactions in situ by using DNA origami as a reaction surface.

DNAThe team recorded the whole dynamic process of the streptavidin–biotin binding reaction. They found that at a streptavidin concentration of 7.6 nM, the binding ratio increased steadily up to nearly 100% within 30 minutes.

This novel single-molecule reaction detection method, at the nanometre scale, may prove useful to study other macromolecule behavior and reaction kinetics, say the researchers.
